I've learned many inspiring stories about Nigeria on this forum. It seems that there are many small businesses there, and entrepreneurs quite often try to adopt Bitcoin one way or another, despite shaky governmental attitude to it. This is yet another inspiring story. I personally think it's especially cool that you accept Bitcoin now, even though the vast majority of your customers are women who aren't familiar with Bitcoin. This creates a good ground to empower Nigerian women, educate them on using Bitcoin (in case customers express interest, of course), as well as promote the usage of Bitcoin more generally. I think that as time passes, you will certainly have Bitcoin sales. Good luck in 2023!
Nigeria is one of those underdeveloped or poor countries so people there needs to work hard. One of the ways that they can think of to help their lives is to run a business. Every business do always start small but as soon as they got successful, this will grow eventually. The emergence of cryptos such as Bitcoin is also an asset for them. These people saw a big potential in BTC so they think it will be a good idea to adopt it on their business. Let's only hope that their government is going to be more friendly with cryptos later on.
From the OP's story his business is a beauty shop so it's normal that most of his customers are women. We shouldn't underestimate them because they also do what other most men can do including taking a risk and BTC is already popular now so they heard and use it even before.
